Gotta Watch: The sky is falling

NASA has announced that it expects a defunct satellite to tumble to Earth today, but scientists can't say exactly when or where. That's got some people worried. This isn't the first time that space junk has fallen from the sky, though. Gotta Watch brings you some of our favorites.

The clock is ticking – NASA says that a satellite will re-enter the atmosphere sometime today. More than two dozen pieces will remain intact and fall to the ground. CNN's John Zarrella looks at where it might hit.

Free-falling – In September 2004, the Genesis space capsule, which was studying the sun, returned to Earth. The only problem - the parachute didn't open. The crash caused the samples that had been collected to be contaminated. Watch the spectacular plunge.

Like a lead balloon – Balloons can cause major damage when they're the size of a football field. This NASA balloon crashed during takeoff in April 2010, smashing into a car and sending one man running for his life.

    NASA: what do you mean you don't know when or where this thing is going to hit!? You are some of the brightest minds in the country! ....Or did you pink slip the smart ones when the Space Program was closed? Sheesh!

      Twin2, you need to study up on orbital mechanics to know exactly why they can not pin point the "landing".

      Seriously! They can determine the exact position of the moon 10,000 years from today but can't tell us when something the size of a bus is gonna fall out of the sky!

      It is much easier to pin-point the landing should NASA has some control over the dead satellite. For now, it is just tumbling freely.

    They really have no idea as in there are equal chances anywhere? Then they say well the earth is 3/4 water so ok, that's 25% chance it lands over land, right? That's not really awesome odds. Just sayin'

      I agree. But then you cut that 25% down to what is actually populated. Yes, this is, in a sense, careless, but there's nothing to fear here folks. Just like every other "scare".

      And I wonder if it hits a populated area, if NASA can be sued.

      Looking at population density maps, you could say at best 1/3 of that land is populated so if we say for the sake of argument water is 75% of the potential landing zone, then only 25/3 percent (8.3%) of the potential landing zone would be populated.

      Now of the 8.3% of the land which contains human habitation (homes towns cities etc) you have to consider a smaller number of that is actual people or structures that could be hit at any given time. So lets be generous, there is about a 5% chance that a building or person would be hit by this debris. Now if you want to calculate the likely hood of you specifically being that person divide 5 by the total population of the planet, and there is a very rough estimate of your individual risk factor.

      You are Significantly more likely to be killed by a car, or a plane, or by lightning.

    CNN .. stop acting like a supermarket checkout tabloid. Get some journalists who can report news .. not manufacture it. The article is true .. but the headline screams "Fire the person who came up with it"

    There's little chance of any pieces hitting anybody, they say. This statement is not based on any fancy NASA science or really complex calculations.... just on the simple fact that the Earth is big and the pieces are small.

    I love statistics.
